Notes. ^(a)The values reported by Deka-Szymankiewicz et al. (2018) were used in this paper. ^(b)There is also a less probable solution with $M_{⋆} = {1.481}_{- 0.042}^{+ 0.045} M_{⊙}, R_{⋆} = {2.182}_{- 0.047}^{+ 0.049} R_{⊙}, L_{⋆} = {4.71}_{- 0.33}^{+ 0.36} L_{⊙}$ $\[M_{\star}=1.481_{-0.042}^{+0.045} ~M_{\odot}, ~R_{\star}=2.182_{-0.047}^{+0.049} ~R_{\odot}, ~L_{\star}=4.71_{-0.33}^{+0.36} ~L_{\odot}\]$ , the age of 2.87 ± 0.31 Gyr, and other parameters consistent within 1 σ. See Table 2 in Pepper et al. (2020) for details. ^(c)The values were taken from Sousa et al. (2021) and Gaia Collaboration (2023), see Table 2 in Castro-González et al. (2024) for details.
